What the hell is that???
A floating object over the people's heads....
I think there's a long way to do in architechture, but these people are starting something interesenting in my humble point of view...
Good luck! and congratulations!

Er, looking at the picture I do not see any 'compression air supports' (which would need a system of vents on the platform) nor do I see any cables. What I do see are two grey metal columns supporting the structure from the middle.

I would like more information on how it is supporting, I tried to find some but came up empty handed.

What I do see are two grey metal columns supporting the structure from the middle.

Well, I wrote those off as being an elevator shaft in the middle of the back end and a stairwell coming up from the back corner, until I realized that neither shows up in the other two pictures. Upon further study, going by the size of the man on the sidewalk as reference, both would be too small for that. In fact, the whole thing looks like a tubularly cross-braced hollow rectangular shell with holes in it. I can see absolutely no purpose to it.

Stairwell? It's all ground level, there is no stairwell. Think of a metrobus station. Same thing. Look at the pictures, those metal columns are in every picture. The purpose of those holes is asthetic when it lights up at night. And those are cross braces do not look structural, they are fluorescent lamps for lighting.

(Yes, there are a *FEW* cross braces that are structual within that mess of lamps.)

How do you figure?! The base of that thing is ten feet or so off of the ground. I stand corrected about the pillars; the near one appeared to be inside about half-way across in the one picture, and in the background in the others. The diagonal, which I guess is actually part of a construction crane, is what I at first took to be a staircase. I didn't even see the other vertical. In any event, those two together could not possibly hold up a cantilever structure of those dimensions unless it's made out of plastic. There's certainly no way you're going to get people in it.

People in it? People go under it. The people have no effect on the weight of the stucture. It's like a metro bus station. It's simply a roof over their heads, nothing more. The people stand ground level.

Why cant it hold it up, its just a big hollow box. (In fact it does hold it up, the picture is proof!) Most of the weight is further removed with the holes cut out of it; besides, the holes allow the air to vent through preventing some pressure forces from developing due to winds.

Well, that picture makes a lot more sense. The perspective was all screwed up in the others.
The reason that I thought of people being in it was that the OP called it a 'building' and a 'railway station'. That might be a language ambiguity. To me, both imply an occupied structure. This appears to just be a big bus-stop.
